GAS HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 688,883, dated December 17, 1 0

Application filed December 21, 1900- Serial No. 40.647. (No model.)

T 0 aZZ whom it may concern- Be it known that I, EDMOND \V. T. RICH- MOND, a subject of the Queen of Great Britain, residing at Summercourt, Romford, Essex county, England, have invented certain new and useful Improvements in Gas Heating Apparatus, of which the following is a specification.

The invention relates particularly to open gas-grate fires for heating apartments; and its general object is to improve their construction and efficiency and to provide for the efficient vaporization of water to render the atmosphere of the room properly humid.

To this end the invention consists of certain improved features of construction hereinafter described in detail.

In the accompanying drawings, Figure 1 is a front View of a gas heating apparatus embodying my improvements. Fig. 2 shows a vertical transverse section thereof, and Fig. 3 is a rear View with the back plate removed. Figs. 4 and 5 are detail views of an efficient burner construction that may be employed in the apparatus.

The frame of the grate is sufficiently indicated by the drawings and does not require detailed description. Within the fireplaceopening is seated a fire-brick structure, which may be described as a fire-brick well, and

may be made in several separate parts or be.

molded and burned in one piece. It consists of a back portion A, preferably having vertical channels to, and which from the point a slopes upwardly toward the front and with a considerably greater angle downwardly toward the front to the bottom opening 1 At the front there is a fire-brick portion B, shown as extending upwardly somewhat short of the horizontal plane in which the angle alies. There are also side walls 0, extending from'the extreme top of the structure down vertically to the level of the upper edge of the part B and then forwardly to join that part at its edges. In this manner a rather deep well-like structure with an opening at the bottom is formed, and within it is disposed the artificial fuel Z, which may be any suitable refractory material that can be heated to luminosity or incandescence by a gasburner working on the Bunsen principle or what is ordinarily known in the art as an atmospheric burner. This fuel is contained in a wirework basket D of a'shape conforming generally to the hollow of a well in the firebrick structure. As shown, its forward edge rests upon the top of the part B and its upper rear edge is considerably above the angle a. Across the front of the frame and above the front fire-brick B is arranged a cast-iron guard D, of open-work ornamental structure, which is secured at its ends by screws to the sides of the frame. Above the fire brick structure is an enlarged chamber or projecting hood E to receivethe products of combustion, which pass therefrom to an outletF at the rear, which may lead to a flue.

As is seen from the drawings, the front of the frame is composed ofa suitable base lying in front of and extending below the front fire-brick B and which projects, as does the hood E, in front of the plane of the parts G of the frame; which surround the opening of the grate. From the parts G of the frame the sides'slope outwardly and rearwardly in all directions. At the top of the frame there is an opening closed by an open-work ornamental removable cover H, within which is seated a water-holder of the shape shown and consisting of an upper semicircularly-covered part H and downwardly-extending legs of bifurcations H passing on each side of the outlet-pipe F, upon which the water-holder rests. Preferably the front of the upper part of the water vessel is inclined forwardly, as shown at h. The open mouth of the water vessel is exposed when the perforated or openwork cover H is lifted, and it may readily be replenished from time to time as required. The frame may be closed at the rear by a back plate I. The temperature of the Water in the vessel H H is raised not only by the general temperature to which it is exposed, but particularly by reason of the contact of its walls with the pipe F, through which the products of combustion escape.

It will be observed that there is achamber in front of the back plate A and in rear of the parts G of the frame, into which air passes through the openings P at the base of the sloping sides of the frame. The air in this chamber is heated by radiation from the frames surrounding the fire-brick structure, and this heated air raises the temperature of the water in the water-holder, which, in connection with the heat imparted to the waterholder by the products of combustion passing through the pipe F, vaporizes the water With sufficient rapidity to properly moisten the air of the room.

Below the opening y in the fire-brick well is located a burner K, which may be of castiron and of the general shape shown in Fig. 4. It has mixing-chambers k 70, with opposite openings, and a series of nipples it, which are fed with the mixed air and gas from the mixingchambers. From the part of the casting ad jacent to the opposite openings k k of the mixing-chambers projects a horizontal plate or flange 70 When placed in position, as seen .in Fig. 2, this flange k rests upon the ledge or shoulder 70 of the frame below the rear Wall A of the fire-brick structure, while the burner rests upon a cross-bar 715 as forming part of the frame. The jet for delivering gas from the openings to the mixingchamb-er K consists of a hollow central portion L, formed with an aperture to receive the gas-pipe connection 0, which enters from the rear of the frame, and with oppositelyprojecting cylindrical portions Z, perforated at the ends for the exit of the gas and exteriorly threaded to receive threaded flan ges or collars Z, having at their outer ends flaring flangeslflwith apertures therein. By running of the frame admit air, which becomes heated by contact with the sides of the fire-brick structure and other parts of the apparatus and after passing by the legs of the waterholder escapes through the openings of the removable cover H or through those of the panels Q Q, adjacent to it.

The gas-supply device or jet described and illustrated is not herein claimed, as it is claimed in another application filed by me December 17, 1900, Serial No. 40,139.

I claim as my invention- 1. In an open-grate gas-heater, the combination of a pipe or flue for the discharge of the products of combustion, with a Water vessel supported thereon, and having depending legs extending down, one on either side of said flue, and an air-chamber into which the legs of the water vessel project.

2. In an open-grate gas-heater, the combi nation of a pipe or flue for the discharge of the products of combustion, a Water vessel supported thereon and having depending legs arranged one on either side of said flue, an air-chamber into which the legs project, and a removable cover closing an opening in the frame, above the top of the water vessel.

3. The combination of the grate proper, a gas-burner therefor, a flue for the discharge of the products of combustion, a frame sur- In testimony whereof I have hereunto subscribed my name.
